It is necessary to provide wheels fitted with pneumatic tires and adapted to run on rails with tlanges,.which are intended to play the same part as the anges o! a'll railway vehicle wheels.

AI These ilanges substantially increase the weight of the wheels, so'that a wheel iltted with pneumatic tires for railway vehicles is' necessarily much heavier than a wheel ntted with pneumatic tires for road vehicles. Furthermore, it

l0 must be said that, railway vehicles being as a rule much heavier than road vehicles, the weight oi the wheel for railway vehicles is consequently stili more considerable. I

Ii' a wheel for railway vehicles is tted with Il pneumatic tires, the possibility ot the tire getting punctured and the resulting necessity oi replacing the punctured tire must be taken into account. It it isnecessary, to this effect, to replace the whole wheel, it will be relatively I0 hard work, owing .to the considerable weight of said wheel.

The invention has for its object a wheel for railway vehicles that is so arranged that it is not necessary to remove the whole wheel in order Il to replace the pneumatic tire. 4

According to the invention the wheel comprisesa partilxedto theaxle andprovided with the guiding ange and. if need be. with a wheel I0 Onthepartilttedtotheaxleissecuredanother partcarryingonlythetireandwhichmaybe relatively light. Preferred embodiments of the invention will be described with reference to the appended drawmerely by way otexample, and in Fig. 1 is a vertical section oi the of the wheel that is secured -to the axle. 1 Fig. 2 is a vertical section of the removable 40 part adapted to carry the pneumatic tire.

`Flg. 3 is a vertical section of a diil'erent embodiment of the invention showing the two parts assembled together.

The partshowninFig.1 comprisesaplate l 48 on. the outer end of which is secured the wheel flange, which may be removable or not. Upon this part may also be tted a brake drum such as 3. The rim 4, provided with its pneumatic tire (Fig. 2) is adapted to be secured to the part shown in Fig. l. To this eil'ect. the rim is mounted on a seat 6. and is kept in position by means ot a continuous circle or of clamps 'l secured by means o! bolts or similar ilxation means 8.

In the embodiment shown in Fig. 3. the rim 55 4 is provided with a ilange 9 which may be directly secured to plate l by means oi' bolts 10 passing through holes 11. In this case. the inner wall oi rimimaybeusedasabrake drum.anddrum3 may be dispensed with.

While in the above description there has been G6 disclosed what is believed to be an eilicient and practical embodiment of the invention, it is to be understood that the invention is not limited by the specliic details as shown, but that it is subject to many and all structural variations which may express the-invention and at the same time comeA within the scope of the appended claims.

What is claimed is:

l. A railway vehicle wheel comprising in combination.. a part permanently securedk to the vehicle axle, a ilxed wheel ilange rigidly mounted on said part, a rim removably secured to said part, and a pneumatic tire adapted to run on the rail. mounted on said rim, and having an outerdiameter substantially smaller than that of the above named wheel ange so that it may coact therewith.

'2. A railway vehicle wheel comprising in combination. a part permanently secured to the vehicle axle, a wheel ilange rigidly molmted integral with said part, a rim, a pneumatic tire mountedonsaidrimadaptedtorunontherail and having' an outer diameter substantially smallerthanthatof said ilangesothatitmay coact therewith. and means on 'the rst mentioned part for fixing said rim thereon, whereby, in the event of atire getting punctured, only the rim need be replaced.

3. A railway vehicle wheel comprising in combination a part permanently secured to the wheel axle. a wheel ilange rigidly mounted integral with said part. a cylindricalseat on said part, a rim, a pneumatic tire mounted on said rim adapted to run on the rail and having an outer diameter substantially smaller than that of said flange so that it may cooperate therewith. and means for securing said rim on said cylindrical seat, whereby, in the event of the tire getting punctured, only the rim need be replaced.

4. A railway vehicle wheel comprising in combination a part permanently secured to the wheel axle, a wheel flange rigidly mounted integral with said part. a cylindrical seat on said part, a brake drum on said part, a rim, a pneumatic tire mounted on said rim adapted to run on the rail and having a diameter substantially smaller than that oi the above named wheel flange so that it may cooperate therewith, and means for securing said rim on said cylindrical seat whereby, in the llO event oi' the tire getting punctured, only-the rim need be replaced.

5. A railway vehicle wheel comprising in combination a disc permanently secured to the vehicle axle, a wheel ilange rigidly mounted integral with said disc, a rim, a pneumatic tire mounted on said rimadaptedtorunontherailaudhavinga diameter substantially smaller than that of the above named wheel ilange, an inwardly extending ange integral with said rim, and means for securing said last mentioned iiange to said disc, whereby, in the event oi the tire getting punctured, only the rim need be replaced.

6. A railway vehicle wheel comprising in combination, a part mounted on the vehicle axle, a iixed wheel flange rigidly mounted on said partra rim removably secured to said part, and a pneumatic tire adapted to run on the rail,

vmounted on said rim, and having an outer diameter substantially smaller than that o! the above named wheel iiange so that it may coact therewith. 7. A railway vehicle wheel having a body portion, an axially extending rim mounting seat on said body portion, a nxed rail engaging ilange rigidly secured to and extending outwardly from said rim mounting seatV and a demountable rim adapted to be secured on said rim mounting seat and carrying a yielding tire adapted to engagethe rail but having its tread portion radially inward oi.' the periphery of said ilange.

8. A railwayA vehicle wheel comprising a body versely extendingperipheral tire seating portion and an integral radially extending rail iiange, an odset formation in the angle joining the rim base portion and the rail tlange limiting the movement of the tire base toward the iiange, and a thickened i metallic bead at the outer periphery oi' the ilange overhanging said oilset formation, and forming therewith and with the ilange, a recess to receive 'the bulge of a pneumatic tire seated on said tire seating portion.

l0. A railway vehicle wheel comprising a boch portion having associated therewith a laterally extending tire seating portion and an annular rail guide flange projecting outwardly tof said wheel body portion beyond the tire seating portion, the outer peripheral portion of said ilange being provided with a solid metallic bead materially thicker than and overhanging the iiange proper and forming with the tire seating portion and the flange a recess to receive the bulg'eof a pneumatic tire seated on said tire seating portion.
